A lens structure with an imaging optical system detachably mountable on a camera body having a focus detecting device capable of detecting the positional relationship between the image of an object formed by the imaging optical system and a predetermined plane and of producing a corresponding detection signal comprises means for adjusting the imaging optical system in response to the detection signal, terminal means to be electrically connected to the camera body upon mounting of the lens structure on the camera body and detecting means adapted to transmit, to the camera body, a first signal in a first state where the imaging optical system is focused to the object at infinite distance, or a second signal in a second state where the imaging optical system is focused to the object at a shortest distance, or a third signal in a third state other than said first or second state.
